Barnet, Enfield and Haringey Mental Health Trust has been rewarded for its innovative partnership with the capital's police force.
The Fixated Threat Assessment Centre (FTAC) set up by the trust and police assesses the level of threat posed to members of the Royal family and prominent politicians from people suffering with mental health disorders.
The team was presented with the top prize for diversity at the Excellence in Total Policing Awards for their work and support to people with mental health conditions.
Maria Kane, Trust Chief Executive, said: “I am delighted that the hard work of the team has been celebrated through this award. How mental health services work with the police is becoming increasingly important.
"We need to make sure that people with mental health problems who come into contact with the police are treated in a way that suits their specific needs."
"This partnership is just one example of how we are working together to make sure this happens.”
FTAC consultant psychiatrist Dr Frank Farnham said: “By making an assessment of an individual the team is often able to put people in touch with their local mental health or primary care services.
“This early intervention allows people with mental health problems to be identified and provided with appropriate treatment much sooner than may have happened otherwise.”
